The Picture type does not exist in 4D Open for Java. If you need to retrieve a picture, you will need to use the BLOB type instead. In your 4D database, you may have a Picture field. In your Java code, you will have the following statement:

mydataArray[0].mDataArray[0].mBlob;

The above example will allow you to retrieve the picture into a BLOB Java field.

The following CreatePicture method will allow you to retrieve the requested picture:

myPicture = Toolkit.getDefaultToolkit().CreatePicture (mydataArray[0].mDataArray[0].mBlob);
